• WWN and LUN associated with the migration source SMI-S enabled storage system that was
assigned to the External port.
For details about the specified values specified for parameters and syntax of each CLI command of
Device Manager and Tiered Storage Manager to be used in tasks, see the HP P9000 Command View
Advanced Edition Suite Software CLI Reference Guide and the HP P9000 Tiered Storage Manager
CLI Reference Guide.
1. Register the migration target storage system and the migration source SMI-S enabled storage
system in HP StorageWorks P9000 Command View Advanced Edition Suite. Use the GUI to
register the storage systems, or run the
AddStorageArray command (Device Manager CLI).
NOTE:
Registering or updating a storage system might take a long time depending on its
configuration or scale, so you need to perform these operations systematically.
NOTE:
If the migration target or source storage system has already been registered, you need to
update the migration target or source storage system in order to obtain the latest
configuration information.
2. Stop the hosts to which the storage systems are connected.
Observe that the following steps (3 - 4) need to be performed while the host is stopped, so you
need a plan that considers host operations.
3. Map the volumes of the migration source SMI-S enabled storage system to the migration target
storage system as external volumes.
Use the GUI to map the volumes or run the AddExternalArrayGroup command (Device
Manager CLI).
4. Allocate the external volumes mapped to the migration target storage system to the host.
Use the GUI to allocate the volumes, or run the AddLun command (Device Manager CLI).
5. Start the host, and then change the target that the host (applications) accesses from the migration
source storage system to the migration target storage system.
Perform this step by using the configuration tools of the host while applications are stopped.
6. Migrate data in the external volumes (migration source) to an internal volume of the migration
target storage system (data migration). Use the GUI to migrate data, or run the following
commands (Tiered Storage Manager CLI):
• CreateStorageTier command
•
CreateMigrationGroup
command
• CreateMigrationPlan command
• CreateMigrationTask command
• ExecuteTask command
7. Unmap the external volumes (migration source) from the migration target storage system.
Use the GUI to unmap (unvirtualize) the volumes or run the DeleteExternalArrayGroup
command (Device Manager CLI).
